4 KB EEPROM

[hugolap]

I want to use the 4 KB EEPROM that is available on some of the Kinetis ARM MCUs.

I am using the MQC  RTOS.

What API calls do I use?

I can't find in in the MQXUG.

All I need is a .h file or something to look at.

Thanks Hugo

Hello Hugo Russouw,

have you opened flexnvm (FlexEEPROM) example in mqx\examples folder ?

Hallo

The MCU does not support this 4 KB EEPROM. :smileysad: (MK60DN512VLQ10)

I can not change to the MK60DX256VLQ10 because I need the program flash and SRAM size.

Can someone tell me if this MCU support Flash as EPROM?

The information I need to save is only going to be set at installation and at upgrade of the system.

Thanks Hugo

Hi Hugo,

the internal flash memory of the K60DN can be erased/programmed at runtime. MQX has Flashx IO driver for this purpose. Check the /mqx/examples/flashx. Part of the internal flash (defined by BSP) can be accessed by fopen(), fread() and fwrite() functions.
